General
Bearing is the component that can fix and reduce the coefficient of friction of the load during mechanical transmission. In other words, when other mechanisms are moving relatively to one another on the shaft which the mechanisms are using for reducing the coefficient of friction during transfer process and keeping the fixed center position of the shaft. Bearing is a very important part of contemporary machinery. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. Bearing can be divided into two types that are antifriction and sliding ones according to the friction properties of moving components.
Component
1. Bearing parts: One of the parts that make up the rolling bearing, but not all accessories.
2. Bearing ring: A ring-shaped part of a radial rolling bearing with one or several raceways.
3. Bearing gasket: A ring-shaped part of a radial rolling bearing with one or several raceways.
4. Loose rib: A detachable, substantially flat gasket with its inner or outer portion as a rib for the outer or inner ring of a radial cylindrical roller bearing.
5. Oblique ring (separable): A separable ring with an "L" cross section, with its outer part acting as a rib for the inner ring of a radial cylindrical roller bearing.
6. Middle retaining ring: A detachable ring in a roller bearing with two or more rows of rollers for isolating the two rows of rollers and guiding the rollers.
7. Stop ring: A single port ring with a constant cross section, mounted in an annular groove, axially positioning the rolling bearing within the housing or on the shaft.
8. Locking ring: A single-mouth ring with a constant cross-section that fits in the annular groove as a retaining ring to hold the roller or cage in the bearing.
9. Spacer: A ring-shaped part that is used between two bearing rings or bearing gaskets or between two half bearing rings or between two half bearing gaskets to maintain a defined axial distance.
10. Seal ring: An annular cover consisting of one or several parts, fixed to a ferrule or washer of the bearing and in contact with another ferrule or gasket or forming a narrow labyrinth gap to prevent leakage of lubricating oil and invasion of foreign objects.
11. Dust cover: A ring cover, usually stamped from a thin metal plate, fixed on a ferrule or gasket of the bearing, and extended toward the other ring or gasket to cover the inner space of the bearing, but not with another ferrule or gasket contact.
12. Retaining ring: A part attached to the inner ring or shaft ring that uses centrifugal force to enhance the ability of the rolling bearing to prevent foreign objects from entering.
13. Rolling body: A ball or roller that rolls between raceways.
14. Cage: A bearing component that partially wraps all or some of the rolling elements and moves therewith to isolate the rolling elements and, in general, also guides the rolling elements and retains them in the bearings.
